I have seen unmarked Exbor hedgehogs, they were exactly the same style as the one in the link to my photos above (cheers David). They were quite a lot smaller (9-10cm instead of 16-18cm), more like 'baby' hedgehogs and their form was a little wonky - the execution was not as successful (but they were still very nice).

On the subject of Czech hedgehogs, I am obliged to mention something my friend Jindrich of GMB fame explained to me a while ago.

For those who do not already know, Czech names often have the habit of describing natural landscape features, as do British names. In discussing this, it transpired the Czech glass designer Mr Pavel Jezek's surname, a man who worked at Skrdlovice as a designer amongst other places, "Jezek," translates as "hedgehog," much as in England we may meet a Mr Edward Fox, Mr Brian Badger etc... Mr Hora is also Mr Hill, etc.. in translation.
